This miracle occured on November 7, 1999, at a Mass held in the minor Basilica of Lourdes. The Archbishop of Lyon, Cardinal Billé, was the celebrant. The concelebrant was the archbishop of France, Cardinal Jean-Marie Lustiger. The Mass was broadcast live on French television.

There were two large hosts on the altar. As you can see in the video, the top host rises up at the beginning of the consecration and levitates in place. The green of the priests' vestments can be seen between the hosts as evidence of the levitation.
